After 20 years of success, the AI-driven town of Concordia plans to expand to Germany, but the plan is threatened when analyst Oliver Miller is found dead.

As the Concordia team grapples with Oliver's breach, they discover he was meeting with an outsider who has since fled the country and is now the primary suspect.

Oliver Miller is revealed to be more than a lonely analyst; he's been leaking private data from Concordia to THE FACELESS, an anti surveillance group. The suspicion arises that the group might still be inside the system. Now, a desperate race against time begins to patch the hack and stop the Faceless before Concordia's hard earned success unravels.

The Gothenburg police close Oliver's case, blaming THE FACELESS for his death. But when a second mysterious death occurs, Isabelle starts to suspect that s omething more sinister is at play. Finding abnormalities in the evidence, she traces it back and wonders if the truth is in fact connected to the founders of the town and Concordia's origins.

As the German launch nears, Isabelle discovers that Conco rdia's birth was no coincidence, revealing an original sin that threatens everything. Her bond with Concordia weakens, while Thea's grows as it offers a solution to her personal struggles. Meanwhile, THE FACELESS aim to sabotage the expansion by targeting Saxony ’s Minister President.

Isabelle uncovers more disturbing truths about the two mysterious deaths. The revelations tear Isabelle’s life apart with h er husband, NOAH, and mother in law and town founder, JULIANE, at the center of it. As the net closes around THE FACELESS, expansion proceeds, driven by Noah and Juliane, with Isabelle left to choose where her loyalties lie.
